I've never seen one. But I could imagine what would be really cool is if you could just place the controller into the middle of the steering wheel, and it still respond as normal, you just could control it with the steering wheel.

That's how I'd like to play any racing games. I know my Dad would too, he has trouble playing racing games without one, but then again the Wii controller will make it much easier.

On the topic of playing SSBB, I might just use the GC controller, it depends on how easy it is to use the Retro controller.

I haven't heard of that rumor. Masahiro Sakurai, the creator of the game, hinted heavily at being able to use the GC controller for the game. "The Wii hardware has sockets for the GameCube controller, too. So I'll just say now that you may not want to throw away your GCN controller yet." So I definitely think you'll be able to after what he said.

I'll definitely try and practice a lot with both and decide for myself how I want to play with it and which I am better with. Once the game is out for awhile, I'm sure one of the two controllers will be used more than the other as the best players will get copied in their controller choice by less experienced players.

I lost my original controller when I went to a lock in, but I'll be using the Wavebird if I use the GC controller.
